Abstract

Die Erfindung betrifft für Flüssigkeiten und Gase selektiv-durchlässige Folien sowie rohrförmige Gebilde auf Basis eines Copolymerisates, das aus copolymerisiertem fluoriertem Olefin, copolymerisiertem Vinylacetat und gege­ benenfalls copolymerisiertem Olefin aufgebaut ist, wobei die Acetatgruppen des Copolymerisates gegebenenfalls zu OH-­ Gruppen verseift sein können, wobei die Folien bzw. rohrför­ migen Gebilde jeweils inhärente latente Strukturumwandel- barkeit besitzen. The invention relates to liquids and gases selectively permeable foils and tubular structures Basis of a copolymer that consists of copolymerized fluorinated olefin, copolymerized vinyl acetate and counter is also built up copolymerized olefin, the Acetate groups of the copolymer optionally to OH- Groups can be saponified, the foils or tubular inherent latent structural transformations possess availability.

Die Erfindung umfaßt ferner Verfahren zur Herstellung der bezeichneten Formkörper sowie Verfahren zu deren Strukturumwandlung. The invention also includes methods of manufacture the designated shaped bodies and methods for their Structural transformation.

Die Erfindung betrifft ferner die Verwendung erfindungs­ gemäßer Formkörper. The invention further relates to the use of the invention appropriate molded body.
